Rated 5 out of 5 by from A new favorite! A truly amazing, simple, affordable, effective and decent looking hat. I've lived in Tilly hats for years and have regularly searched for a more affordable alternative. This hat is it while also being lighter weight, and cooler on hot days. The hat looks decent, the brim maintains a good shape. The drawstring stabilizes the hat nicely both behind the head and under the chin. The combination of the synthetic headband and back venting keep the hat more comfortable on hot days than any other brimmed hat I've tried. I also get more complements of looking good in this hat than I ever have with any other hat, although, personally, I think my Tilly is better looking.

Rated 5 out of 5 by from Outstanding general purpose summer hat! The large is a true Large/XL and fits my 23" head pretty well. The hat is fairly light and very comfortable to wear. Fairly cool. The mesh you see in the photo actually has some type of wicking honeycomb material underneath it. It lets a lot of light and air through without causing sunburn. The brim is medium sized and gives my face good coverage but no further out. The brim also has a bead sewn into the outer edge that gives it some rigidity. It will hold it's shape and keep you shaded in a 25 MPH breeze. Any higher and it starts to deform. It's stiff enough that you can't fold it, but it can be stored flat with things on top of it. The hat will not keep it's shape without being on your head. This hat is a delight to hike or walk in. The brim is high enough so that is does not interfere with peripheral vision and I get to enjoy all of the sights! I also don't run into tree branches wearing this hat. There is a small pocket under the crown. Nice tailoring and good quality materials. It feels well made. Nylon and polyester construction so sunscreens might damage it. Perspiration stains will probably be permanent. The web photo does not do it justice. This is a very attractive hat and it looks good on my wife as well. Since this is the first hat that I have ever truly liked I am going to go back and buy a few more while they are still available.

Rated 5 out of 5 by from Comfortable, lightweight, great for backpacking To REI: you'll be delighted to learn that yes, I will accept payment for this review; and yes, I'm open to job offers, ahem. --------------------------------------- First, a word on bucket hats: This hat is not quite as light as most synthetic bucket hats, but the big flaw with bucket hats is that they don't have structure, and let's face it: you're looking at non-bucket hats right now because you don't want the grumpy fisherman look, and you want a predictably clear field of vision at all times. So let's move on... Compared to other non-bucket hats: I've tried all the other structured (non-bucket) sun hats on this site (as of summer 2015), and the closest contenders in terms of weight, bulk, sun protection, breathability, comfort and looks are the the Sunday Afternoons Charter Hat and the Tilly Hat. Though the weight difference between any two sun hats is not huge, you'll feel that difference when it's sitting on your head and you're hiking for miles in the heat. The Charter Hat will give you slightly more comprehensive sun protection with its wider brim, and it's good for casual use in a super hot place, but it doesn't look as good, and more importantly its weight and bulk will feel oppressive for hiking/backpacking purposes, and thus I would dare say it's not activewear (you'll soak that thing in sweat). The Tilly Hat is a good contender on all categories, and though it's a good fishing hat / rich-guy-on-a-boat hat, it's not ideal for backpacking or major activity. The REI vented hat is more "set it and forget it," as it were. The vent on the back is a tiny bit odd in a visual sense, but despite this, I can honestly say it's overall the best looking sun hat available through REI as of this review. The semi-fedora cut is killer. Looks.

Rated 4 out of 5 by from Buying A Second One I worked in the Grand Tetons last summer and bought this hat for its wider brim and venting. I wore it every day especially when hiking and leading walks. It is light and vents well. Alas, somehow at the very end of the season, I misplaced it. I like it enough that I am buying another.

Rated 5 out of 5 by from Great Hiking Hat Wore this hat in Africa on a photo safari. Provides excellent sun protection. Vent in the back kept me cool. You can also take this hat and stuff it into your backpack if you need to wear it later. Pull it out and it the brim reforms it shape. Have not hand-washed yet, but expect it will hold up well. It's a keeper!

Rated 5 out of 5 by from Awesome hat, great fit. Read the reviews in advance of a summer Yosemite trip up Glen Aulin, desired neck coverage from the sun. Great fit, hideable strap, worked wonderfully under the necessary mosquito head net. The vent provided great airflow, the sweat band didnt keep up with my profuse flow but add a Buff and your solid.

Rated 4 out of 5 by from Comfortable hat I tend to sunburn fairly easily so bought this hat to protect my head, ears, nose from the sun while hiking. Worked ok on the hikes i've been on though it does keep the heat inside as do most hats. Brim is stiff enough that it doesn't hang down to impede ones view like some of the floppy hats..Also wore it in a short rain shower, didn't soak through. Only complaint I have is the strap, wish it was removable.

Rated 5 out of 5 by from Great hat for work or play Nice and cool hat and added protection for working in the garden on sunny days or hiking through the woods.

Has the REI Vented Sahara Outback Hat been discontinued, specifically the L/XL size? I was shopping for similar hats for my husband and this one was the one I was like the most. I hope it's not gone forever!!

What are the care instructions?  Can you wash it in the washing machine? 

Asked by: stlbpw
We would recommend washing the Vented Sahara Outback Hat by hand, and air drying it. Nathan Sport Wash would be a fine choice.

Does this hat protect the back of the neck from sun and heat? I noticed it doesn't have a back flap.

Asked by: cc35
​This has does not have a cape that protects the back of your neck. It has limited protection from the brim only.

Is the S/M size discontinued? I have a small 22" head, so I can't wear the L/XL size.

Asked by: ACoff
The s/m size of the Vented Sahara Outback Hat has not been discontinued. We will get more starting in early 2017 (information as of August 2016).

I seem to be right in the middle of s/m and l/xl at 22 1/2 inches. What do you advise and is there a way to adjust? Will it shrink any?

Asked by: Lake Superior
Based on the information provided, it sounds like a S/M is the best choice for you as it fits individuals with a head circumference of 21.5 - 22.75 inches. The hat is not adjustable and it does not shrink.

The sizes appear in the pull-down menu as S/M and L/XL. Are those 2 different sizes or 4 different sizes? How do I specify XL?

Asked by: chaoticmoss
The sizing is correct; a size S/M encompasses both the sizes small and medium (i.e. head circumference 21.5 – 22.75 inches).
